LRAD 500X

Main Power Switch
This is the main power on/off switch for the unit. This is a double-pole single throw
(DPST) switch that is wired in parallel for redundancy.
Resettable Breaker
The resettable breaker provides over-current protection on the input in the event of an
internal short or system failure.
Sound Projection Switch
The sound projection switch allows the user to alter the directivity or “beam width” of
the unit’s acoustic output between wide and narrow settings. The wide setting can be
used for broadcasting messages in open areas where reflections from nearby buildings
or other objects will not interfere with the intelligibility of the broadcasted message.
The narrow setting can be used in urban environments or other settings where nearby
structures can cause echoes and reflections that can degrade the intelligibility of the
broadcasted message.
The graphic on the switch label represents wide and narrow “cones”
of projected sound.
Volume Control
The volume control knob works in the same way a traditional volume knob on a stereo
system works. It controls the gain of the system and provides a continuous range of
output levels.
WARNING: The LRAD-500X is capable of producing extremely high sound pressure
levels. Always be sure to have the volume control at its minimum setting when
powering on the unit, and raise the volume to maximum only after taking appropriate
precautions for yourself and nearby personnel.
Operators must wear hearing protection when raising the volume level of the unit
past the red zone marked on the volume control. Prolonged exposure to excessive
sound pressure levels can cause hearing damage.
